IMPROVED LUBnIcA-rme nnvrgs.

Be it known that I, THOMAS S. BROWN, of Poughkeepsie, in the county .ofDutchess, and State of New York, have invented a new and improvedSelf-oiling Device for crank-pins and other journals of machinery; and Ido hereby declare that the following is a full, clear, and exactdescription thereof, which will enable others skilled in the art to makeand use the sari 1e, reference being had to the accompanying drawings,forming Part of this specification, in which-- Figure 1 is a sidesectional view of myfinventiou' taken in the line :r' x, fig. 2.

Figure 2, a front sectional view of the same, taken .in the line y y,fig. 1.

Figure 3, an under view of an inverted-plan of the stopper of theoilfountain.

Similar letters of reference indicate like parts.

The object of this invention is to obtain aself-oiling device forcrank-pins and other journals of machinery,

which have either a rotary or reciprocating motion, to keep the oil inthe fountainiu a suflicien't state ofagitation to cause the same to befed to the journal in requisite quantity to insure perfect lubrication.I

The accompanying drawings represent the invention applied to a crank-pinor crank journal, which is designated by A, the pitmanor'conne'cting-rod being designated by B, and Grepres'enting the hearingwhich encompasses the journal A. The bearing 0 is composed of ."twoparts, a b, the part a having a circumferential projection, c, at itscentre, grooved, as shown at d, to receive th'e prongs e e of the pitmanor connecting-rod B lhe other part, 6:, of the bearing is cast orprovided with lugs or ears,through which the prongs e e of the pitman'or connecting-rod pass, saidiprongslhaving screw-threads cut on "themto receive nuts, g, a plate, It, being fitted on the prongs-at the outersides of the nuts and n'u-tsi screwed on'the prongs at the outer side ofthe plate Inns shown clearly in fig. 1. 7 By this arrangement-it'will beseen thatv the parts ob of the hearing are firmly secured to: thejournal A, and the 'pit'mansecured to the hearing. The part b of thebearing is cast or otherwise provided with anoil-chamber, D, having ascrew-plug or stopper, E, in its upper vend, and F is a tube' :oxtendingup within theoil-chamber, and communicating with a passage, 0, whichextends downward'through the part bof the bearing, so as to convey oilfrom the chamber D down to the journal A, as clearly shown in fig. 1.The under surfacev of the plug or stopper E hash groove, j, madecentrally across it, with a recess or cavity, k, at its centre, whichrecess or cavity is "dircctly over the tube E when the plug or stopper Eis screwed into the oil-chamber D. The-charnb er is supplied with oil orother suitable lubricating material, and-:th e oil in said chamber, astho ,crankspin or journal, 1A, rotatesbr otherwise moves will beagitated and thrown against the lower cnd of the plug or stopper E,and'the groovej will convey the oil over the tube F, the former droppinginto the latter which'conveys itto the'journal A.

This invention is applicable to all journals of machinery whichhaveinotion sufiicient to cause the oil to be thrown agninstor. brought incontact with the lower end of the plug or stopper over .the tube F. Theoperation is sure and cfiicient. There can be no over supply or waste ofoil, and theperfect lubrication of the journal is rendered certain aslong as any-oil is contained in the chamber D. I

I claim as new, and desire to secure by Letters Patentchamber D, in thepart b of the bearing G, through which extends the-tube F, communicatingwith the passage 0, in combination with the plug E and journal A,arranged and operating substantially as herein described and for thepurpose s )QOlllOLl- I further claim the plug or stopper E of theoil-chamber D, grooved at its under side, in combination with the tube Fand passage 0 in the bearing, substantially as and for the purposespecified.

THOS. S. BROWN.
